Preview documents, videos, music, and more with a mouse hover.

- (2023-11-08) Nicole Ahmed: Excellent extension and a very responsive developer. I've tried lots of the office extensions on chrome and most are rubbish, some are malicious. This extension is innovative and so useful. The peek window to preview files before fully opening them is excellent, The pop out window is great because you resize the window and have it open alongside your other work. This doesn't have editing capabilities, just viewing. But is very useful for viewing documents conveniently. Highly recommend

- (2021-11-19) Roadrunners Garage Doors: I really liked this extension when it worked but now it seems like it doesn't work at all regardless of what website I am on and what link it is.
- (2021-02-18) Aatif Iqbal: Fantastic extension, works perfectly
- (2019-11-16) 黒坂文武(Fishmanzero): Useful tool! Looking forward to an option for preview size.
- (2019-03-26) Santiago Galán: Very usefull!
- (2019-01-11) Mojtaba Vahdati: Very interesting idea, but it works for none of the YouTube videos neither from inside YouTube nor from the Google video search page (Google.com/Videos) results which is a real drawback. But I gave 5 stars because I really love the extension purpose and because it's open sourced. Great job Mr Daven Port.
- (2017-05-21) Anton K: A very useful extension for all those docs you'd rather preview before downloading. Some minor issues, still worth using.
- (2017-05-02) I discovered this extension thanks to Corbin's Android Police post, and it's really helpful.
- (2016-09-15) Donavon Lasseter: Worked for about half a second. Chrome freezes when in use. Have to restart my computer.
- (2016-01-08) Hannah Katagi: Great extension! This should get more exposure!
- (2015-12-08) Matthew K: Really neat idea. Can be a little intrusive (pops up quick and often), so an option to only pop up when holding a hotkey would be ideal.
